Socket通信和多线程的总结

1.ServerSocket进行多线程接收

package com.yh.chat;

import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;

public class ChatServerSocket {
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        ServerSocket serversocket = null;
        Socket socket = null;
        try {
            serversocket = new ServerSocket(5005);
            while (true) {
                socket = serversocket.accept();
                ChatAcceptSocket accept = new ChatAcceptSocket(socket);
                accept.start();
            }
            // 发送信息
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

package com.yh.chat;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.Socket;

public class ChatAcceptSocket extends Thread {
    private Socket socket;

    public ChatAcceptSocket(){}
    public ChatAcceptSocket(Socket socket){
        this.socket=socket;
    }
    @Override
    public void run() {
        // TODO Auto-generated method stub
        InputStream is = null;
        BufferedReader br = null;
        // 接收信息
        try {
            is = socket.getInputStream();
            br = new BufferedReader(new InputStreamReader(is, "UTF-8"));
            String info = "";
            while ((info = br.readLine()) != null) {
                OutputStream os = socket.getOutputStream();
                byte[] replys = info.getBytes();
                System.out.println("广播："+info);
                os.write(replys);
                os.close();
            }
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

}

2.客户端进行连接（代码省略，参考：流式套接字：基于TCP协议的Socket网络编程（案例1））

这里ServerSocket进行的广播仅限当前线程的中的socket，不会给其他线程的socket发送数据。
